I see on John's website that Arthur St. Clair was listed as the 7th Pres. of
the Continental Congress but now I have come across another list taken
originally from the Biographical Directory of the American Congress.
1774-1949.

An addition to Laurel's run down of
Sinclair/St Clair history. Yes there was a US President. This
information came from Dan Valentine's book of little known facts
entitled Spirit of America essay no. 9. Because there was an 8 year
gap between the founding of our nation and the ratification of the
constitution (1781-1789) there were 8 people who held the position of
elected president before George Washington. Each of those years the
president of the US Continental Congress was the prime authority of
the nation. They were elected for one year. Those men in order
were:

John Hansen

Richard Henry Lee

Elias Boudinot

Thomas Mifflin

John Hancock

Nathaniel Gorhan

Arthur Sinclair
(Who was also the Gen Arthur Sinclair [he spelled it St. Clair jsq])
